I just researched, bought, and downloaded this software. When I enter the serial number I’m given, I get “Could not register software. Invalid serial number. Please enter valid serial or contact support.” I thought I would just activate it as a trial in case it takes 24 hours to get going or something. When I try to do that, I get the same message. What do? This sounded great, but I’m worried I’ve been scammed or something…
